The wind turbine efficiency increases by controlling the rotor speed to its optimal value. A nonlinear controller, which is robust towards uncertainties in the dynamic plant model and unknown disturbances, is designed for better capture of rotor speed. This paper focuses on an effective wind speed based complementary sliding mode controller (CSMC) designed for wind turbine. The main objective of the controller is to extract the maximum power from wind at region 2 (below rated wind speed) with minimum oscillation on the drive train. The controller stability is validated by Lyapunov function. The proposed and existing control algorithms are validated using a FAST 600kW model which is developed by NREL (National Renewable Energy Laboratory). The efficacy of the proposed controller is validated by comparing it with typical nonlinear controller such as sliding mode and integral sliding mode controller. A detailed simulation is performed for typical and proposed control strategies for different mean wind speed profiles. The simulations results shows that, complementary sliding mode controller gives better performance than typical control strategies.
